Hey guys,
Micron ddr3 has been out for over 6 months now and there have barely been any sticks killed. I have however heard from several people killing their micron ddr3 memory and those few reports are enough to draw some conclusions.
I thought id share them with you to make sure you dont kill your precious D9GTR GTS GTN etc
micron ddr3 doesnt seem to slowly degrade like micron ddr2!
it slightly degrades at high vdimm even with good cooling, but then runs more or less stable at the same speeds without any problems... until it suddenly dies.
the problem is that each chip and thus each stick acts diferent and might tolerate more or less voltage. since the chips and sticks dont degrade steadily its almost impossible to predict what stick will be able to run with what voltage safely. seeing as most of the memory barely performs any faster at high voltages compared to reasonable voltages i highly recommend you to think twice at what speed and thus at what voltage you run your micron based ddr3 with.
WARNING
Whatever voltage you decide to use, make sure you meassure the voltage on your mainboard using a multimeter or at least check how much other boards of the same model and revision overvolt vdimm. some mainboards are overvolting vdimm by as much as 0.1v (2.2v bios = 2.3v real)
1.9v officially max voltage CellShock recommends/warrants
2.0v seems very safe for 24/7
2.1v seems safe for 24/7
2.2v can damage/kill memory regardless of cooling
2.3v can damage/kill memory regardless of cooling
2.4v+ can damage or kill memory regardless of cooling after hours-months, depending on the board, the batch of chips and the cooling used
sticks that were reported damaged/dead or degraded with the respective vdimm values
vdimm= REAL vdimm, not what was set in BIOS
2.15v 1
2.20v 1
2.25v 1 1
2.30v 2 2
2.35v 2 1
2.40v 4 7
temperature:
despite of ddr3 running much cooler than ddr2, the chips are still sensitive to high temperatures and will degrade when they get too hot!
even at high voltages a silent casefan will be enough to cool the memory, so its really not worth letting your ddr3 sweat
